[PATCH v5 3/4] mmc: sdhci-of-arasan: Add structure device pointer in probe

From: muhammad . husaini . zulkifli
Date: Thu Oct 08 2020 - 14:22:10 EST


From: Muhammad Husaini Zulkifli <muhammad.husaini.zulkifli@xxxxxxxxx>

Add struct device *dev in probe func() so that it can widely use in
probe to make code more readable.
